Credit Applications

Prerequisites

Before diving into the integration process, ensure you have the following:

Sign up for a Drivly account
Create a DRIVLY_API_KEY
Have a basic understanding of REST APIs
A secure environment for handling sensitive data

Always perform Credit Application operations server-side to secure API keys.

Overview

The Credit Application process enables users to secure auto loans, providing them with information on loan amounts and interest rates. This guide covers various scenarios, including applications for primary applicants and co-applicants, with or without trade-ins.

Implementation Options

You can implement the Credit Application API using either the Drivly SDK or the API:

Follow the steps below to set up using the SDK.

To get started, you will need to install the Drivly SDK.

yarn add @drivly/commerce

Create a singleton instance of the SDK.

We will use the DRIVLY_API_KEY and will start in sandbox.

sdk.ts
Copy
import { SDK } from '@drivly/commerce'

export const sdk = SDK({
  apiKey: process.env.DRIVLY_API_KEY as string,
  environment: 'sandbox',
})

Now, we can export the sdk to use in our application

Make a function to CREATE the Credit Application.

credit.action.ts
Copy
'use server' // Next JS specific for server actions

import { CreditApplication } from '@drivly/commerce'
import { sdk } from './sdk'

type CreditData = Omit<CreditApplication, 'id' | 'createdAt' | 'updatedAt'>

export const createCreditApp = async (data: CreditData) => {
  try {
    // Change to 'Production' for live applications
    const environment = 'Development'

    const result = await sdk?.commerce.creditApplications.create({
      doc: { environment, ...data },
    })

    console.log(result)
  } catch (error) {
    console.error(error)
  }
}

We might need to CREATE a Trade, we will need a few more functions.

In cases where a trade-in is involved, we need to create a trade record for the vehicle being traded.

Copy
'use server' // Next JS specific for server actions

import { sdk } from './sdk'
import { createLienholder, getLienholderId } from './lienholder.action'
import { CreateTradeParams } from './shared.param.types'
import { createCommerceVehicle, getCommerceVehicleId } from './vehicle.action'

export const createTrade = (params: CreateTradeParams) => {
  try {
    const { data, id: creditApplication } = params
    const { lienholder: companyName, payoff, odometer, ...rest } = data
    let lienholder: string | undefined

    if (companyName) {
      const prevLien = await getLienholderId({ companyName })

      lienholder =
        prevLien !== 'Lienholder not found'
          ? prevLien
          : await createLienholder({ data: { companyName } })
    }

    const prevVehicleId = await getCommerceVehicleId(rest.vin as string)

    const vehicle =
      prevVehicleId !== 'Vehicle not found'
        ? prevVehicleId
        : await createCommerceVehicle({ data: rest })

    if (vehicle === 'Failed to create vehicle') throw new Error(vehicle)
    if (lienholder === 'Lienholder not created') throw new Error(lienholder)

    const result = await sdk?.commerce.trades.create({
      doc: {
        creditApplication, // Credit Application ID
        lienholder, // Lienholder ID
        odometer,
        tradeInPayoffBalance: payoff,
        vehicle, // Vehicle ID
      },
      depth: 0,
    })

    if (!result) throw new Error('Trade not created')

    return result.doc.id
  } catch (error) {
    console.error(error)
  }
}

We can use https://commerce.driv.ly/api/creditApplications to create and manage Credit Applications.

Create an environment variable for your API Key.

.env
Copy
DRIVLY_API_KEY='YOUR_API_KEY'

Make a function to CREATE the Credit Application.

credit.action.ts
Copy
import { CreditApplication } from '@drivly/commerce'

type CreditData = Omit<CreditApplication, 'id' | 'createdAt' | 'updatedAt'>

const url = 'https://commerce.driv.ly/api/creditApplications'

export const createCreditApp = async (data: CreditData) => {
  try {
    // Change to 'Production' for live applications
    const environment = 'Development'

    const response = await fetch(url, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: `${process.env.DRIVLY_API_KEY}`,
      },
      body: JSON.stringify({ environment, ...data }),
    }).then((res) => res.json())

    console.log(response)
  } catch (error) {
    console.error(error)
  }
}

We might need to CREATE a Trade, we will need a few more functions.

In cases where a trade-in is involved, we need to create a trade record for the vehicle being traded.

Copy
import { createLienholder, getLienholderId } from './lienholder.action'

import { createCommerceVehicle, getCommerceVehicleId } from './vehicle.action'

const url = 'https://commerce.driv.ly/api/trades'

export const createTrade = (params: CreateTradeParams) => {
  try {
    const { data, id: creditApplication } = params
    const { lienholder: companyName, payoff, odometer, ...rest } = data
    let lienholder: string | undefined

    if (companyName) {
      const prevLien = await getLienholderId({ companyName })

      lienholder =
        prevLien !== 'Lienholder not found'
          ? prevLien
          : await createLienholder({ data: { companyName } })
    }

    const prevVehicleId = await getCommerceVehicleId(rest.vin as string)

    const vehicle =
      prevVehicleId !== 'Vehicle not found'
        ? prevVehicleId
        : await createCommerceVehicle({ data: rest })

    if (vehicle === 'Failed to create vehicle') throw new Error(vehicle)
    if (lienholder === 'Lienholder not created') throw new Error(lienholder)

    const response = await fetch(url, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: `${process.env.DRIVLY_API_KEY}`,
      },
      body: JSON.stringify({
        creditApplication, // Credit Application ID
        lienholder, // Lienholder ID
        odometer,
        tradeInPayoffBalance: payoff,
        vehicle, // Vehicle ID
      }),
    }).then((res) => res.json())

    if (!response?.doc) throw new Error('Trade not created')

    return response.doc.id
  } catch (error) {
    console.error(error)
  }
}

Now that we have the data formatted, we can send the request to create the Credit Application.

Copy
import { createCreditApp } from './credit.action'

const creditAppId = await createCreditApp(creditData)
console.log(creditAppId)

Always perform Credit Application operations server-side to secure API keys.

Primary and CoApplicant

Danny’s wife Michelle found a car she loves. They want to secure a loan to buy the car. They go to your website and fill out a form to find out how much of a loan they can secure.

When both Danny and Michelle want to secure a loan for a car they love, their journey through your website will be slightly different to account for the additional information needed from the co-applicant. Here’s how to guide them:

Direct Both Applicants to the Credit Application Form.

Ensure your form is set up to handle input from both the primary applicant and the co-applicant. It’s crucial to clearly label which sections pertain to each applicant to avoid confusion.

Include identical fields for both the primary applicant and the co-applicant.

Collect and Format Data for Both Applicants.

While collecting the data, remember to gather information from both Danny and Michelle, treating Michelle’s data as the coApplicant’s or vice-versa. The data structure for the coApplicant will mirror that of the primaryApplicant.

For the relationshipType in the coApplicant’s data, select the appropriate option that describes their relationship to the primary applicant.

Format Data
Copy
const creditData = {
  sendTo: 'RouteOne',
  state: 'DRAFT',
  environment: 'Production',
  // Previous fields for primaryApplicant
  coApplicant: {
    // Repeat the fields from primaryApplicant,
    // filling in Michelle's information
  },
  hasCoApplicant: true,
  // Other necessary fields (vehicle, applicationType, etc.)
}

Send the Request.

Now that we have the data formatted, we can send the request to create the Credit Application.

Copy
import { createCreditApp } from './credit.action'

const creditAppId = await createCreditApp(creditData)
console.log(creditAppId)

Always perform Credit Application operations server-side to secure API keys.

Primary with Trade

Danny is looking to trade-in his 2011 Lincoln Town Car for a 2023 Genesis G80. He wants to secure a loan to buy the car and trade-in his old car. He goes to your website and fills out a form to find out how much of a loan he can secure.

In cases where Danny is looking to trade in his current vehicle as part of securing a new loan, the process involves an additional step to include trade-in information.

Guide Danny to the Enhanced Credit Application Form.

Adjust your form to include a section for vehicle trade-in details.

tradeInVehicle

Trade-In Object

Ensure the form includes fields for the primary applicant’s personal, residence, employment, and vehicle information.

Collect Information Including Trade-In Details.

Apart from collecting the standard application information, you’ll need to gather details about the vehicle Danny intends to trade.

tradeInData
Copy
const tradeInDetails = {
  make: 'Lincoln',
  model: 'Town Car',
  year: '2011',
  payoff: '7000',
  // Additional fields as necessary
}

Create a Trade.

Before sending the Credit Application, you’ll need to create a trade-in record for Danny’s vehicle.

Copy
import { createTrade } from './trade.action'

const tradeInId = await createTrade(tradeInDetails)
console.log(tradeInId)

Always perform Credit Application operations server-side to secure API keys.

Send the Request with the tradeInId

Copy
const creditData = {
  sendTo: 'RouteOne',
  state: 'DRAFT',
  environment: 'Production',
  applicationType: 'PURCHASE',
  financeAmount: 65000,
  downPayment: 5000,
  primaryApplicant: {
    // Primary applicant data
  },
  vehicle: {
    // Vehicle data
  },
  trades: [tradeInId],
}

const creditAppId = await createCreditApp(creditData)
console.log(creditAppId)

Primary and CoApplicant with Trade

Danny and Michelle are looking to trade-in their 2011 Lincoln Town Car for a 2023 Genesis G80. They want to secure a loan to buy the car and trade-in their old car. They go to your website and fill out a form to find out how much of a loan they can secure.

For scenarios involving both a primary and a co-applicant intending to trade in a vehicle, combine the steps and considerations from the previous scenarios.

Guide Both Applicants to the Enhanced Credit Application Form.

Ensure your form includes sections for both applicants and trade-in details. Ensure clarity and ease of navigation within the form.

Collect Information Including Trade-In Details.

Gather information from both Danny and Michelle, including details about the vehicle they intend to trade.

Create a Trade.

Before sending the Credit Application, create a trade-in record for the vehicle Danny and Michelle intend to trade.

Copy
import { createTrade } from './trade.action'

const tradeInId = await createTrade(tradeInDetails)
console.log(tradeInId)

Send the Request with the tradeInId

Copy
const creditData = {
  sendTo: 'RouteOne',
  state: 'DRAFT',
  environment: 'Production',
  applicationType: 'PURCHASE',
  financeAmount: 65000,
  downPayment: 5000,
  primaryApplicant: {
    // Primary applicant data
  },
  coApplicant: {
    // Co-applicant data
  },
  vehicle: {
    // Vehicle data
  },
  trades: [tradeInId],
}

const creditAppId = await createCreditApp(creditData)
console.log(creditAppId)
